With 1,170 different conversions among 132 units spanning 15 conversion modes (everything from length and volume to electric charge and radioactivity), Batch Convert is one of the most complete unit converters out there. Yet at only 2,977 bytes, it's still one of the smallest in size. However, what makes Batch Convert different—and what gives it its name—is that it's intuitive. It's extremely easy and fast to convert between different units—the answer is updated instantly and automatically as you type. See the screenshots for a demo!
